BINDER-HEAD FOR I-IARVESTERS.

To all whom it may concern:

Be it known that I, HERMAN E. Hurr- MILLER, of St. Paul, county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Binder- Heads for Harvesters, of which the following is a specification.

My invention relates to a mechanism for securing a cord, made usually from flax fiber, around the bundle of grain, taking the place of the well known knotter mechanism usually employed for this purpose.

The object of my invention is to simplify and improve certain mechanical devices shown and described in the U. S. patent of Joseph L. Ware dated October 1, 1912,

No. 1,039,853, on binder-heads for harvesters, which patent has been assigned to the IV are Grain Binder Attachment Company, a corporation, also assignee of this invention and application.

The invention consists generally,-First,

part of this specification, Figure 1 illustrates a vertical sectional view through a portion of a binder with my invention applied thereto, Fig. 2 is a side view, partially in section,

showing the mechanism for feeding the rib bon, Fig. 3 is a similar view, also in section,

taken on a line substantially at right angles,

Figs. 8, 9 and 10 illustrate the position as-; sumed by the cord and the manner of fold- 1' ing the clip thereon.

operating through the deck in the usual way, 4 the needle, the operation of which and the packer arms is controlled by a trip lever 5 This lever is operated through mechanism, not shown, at the opposite side of the deckin the usual way in machines of this kind. 6 represents the drive shaft on wh ch the knotter head is mounted. The frame 7 of the head has a hub 8, (see Fig. 5) that is mounted on the shaft 6 and on this frame 7 the clamp forming and folding mechanism is arranged. A disk 9 is secured on the shaft 6 and provided with cam surfaces which will be hereinafter referred to.

As shown in Fig. 1, the frame 7 has a plate 10 supporting standards 11 which carry a spool 12 on which the ribbon 13, preferably of metal, is wound. This ribbon consists of a thin strip of metal and the pieces cut therefrom are readily folded to form a clasp or binder. Rollers 14 and 15 are provided in position to receive the end of the ribbon (see Figs. 2 and 3). The lower roller 14 is mounted on one end of an arm 16 which is pivoted at 17 in the frame and a spring 18 mounted on an upright stud 19 engages the opposite end of the arm 16 from the roller 14 and holds the said lower roller toward the upper one with a yielding pressure. The upper roller 15 is journaled on a stud 20. The lower roller has a gear 21 at its inner end meshing with a similar gear 22 on the upper roller. An arm 23 is loosely mounted on the shaft of the upper roller and carries a pawl 24 which engages the gear of that roller. (See Fig. 2). A link 25 pivotally connects the arm 23 with a loop 26 that is mounted in a vertical rock shaft 27 which has bearings in the frame 7. The lower end of the vertical shaft 27 carries a horizontally operating cord severing knife 28. When the shaft 27 is rocked to swing the severing knife around into the throat of the binder head preparatory to cutting the cord the arm 22 will be swung toward the left as viewed in Fig. 2, the pawl 24 sliding on the teeth of the ratchet, and upon the return movement of the rock shaft 27 and the knife 28, the arm 22 will be swung back to its normal position and the rollers 14 and 15 will be revolved to feed the ribbon a sufficient distance to form a clip.

The upper end of the shaft 27 is provided with a pinion 29 which meshes with teeth 30 mounted on a reciprocating bar 31. This bar is slidable in a' guide way provided in time to rotate the shaft 27 to set the cord severing knife 28 in its working position and operate the ribbon feeding rollers. The.

ribbon is fed through a slot 35 into contact witha stop 36, thus insuring clips of the same length at each operation ofthe machine.

A stationary knife 37 is mounted in the frame of the head, over which knife the ribbon is fed. A movable knife 38 is arranged above the projecting end of the ribbon and is vertically movable with respect thereto and its lower edge has a groove 39 therein which is adapted to receive the upper edge of a plunger 40. See Figs. 2 and 5"). A lever 41 (see Fig. 5) is pivoted at 42 on the binder head frame and is provided at one end with an anti-friction roller 43 which contacts with a cam surface 44. The lever 41 is operatively connected with the vertically moving knife 38 by a rod 45.

Through this connection the knife 38 is reciprocated vertically as the lever 31is oscillatedl This lever 41 carries jaws 46 having recessed faces 47 which coiperate with a stationary jaw 48 and grip the cord during the operation of folding the clip. The lever 41 is normally held in its withdrawn or retracted position. by a spring 48. The plunger 40 reciprocates in the guide-way 49 in the frame 7 and in a groove 39 in the lower end of the knife 38, the forward end of the plunger engaging the clip 'to move it lengthwise into contact with'the faces 47 of the jaws 46. The plunger 40 has an adjustable connection 50 with a lever 51 which is pivoted at 52 and is provided with an arm 53 carrying rollers 54 and 55 between which the edge of the cam disk 9 is inserted. When the'disk is revolved, the cam surfaces thereof will cause the oscillation of the lever 51 and a positive reciprocation of the plunger. mounted on the plate 10 between which and the frame 'the'lever 51 is oscillated. The,

'cord .57, composed of flax fiber or other'su-itable material, is threaded through the needle in the usual way and passes up to a cord.

holder, consisting of a disk 58 having a hub 59 fitting within a sleeve 60. A pin 61 is mounted in the sleeve and engages a groove 62 in the hub; A disk 63 has a spindle 64 loosely fitting within the hub ,59 I and a flat spring 65 is mounted on the frame 5 of the binder head and attached to the spindle 64, the tension of the spring holding the disk 63 against the disk 58 with a yield- A guide 56 is preferablying firessure. Teeth 66 are preferably pro vided on the inner face of the disk 63 to aid in holding the cord between the disks. 'At' a predetermined noint in the formation of a bundle of grain the needle will carry the cord up around the rear of the bundle in the usual way, delivering it across the-free end of the cord which is held between the clamp ing disks of theholder, one end of the cord being gripped in the cord holder. which is free to turn in its bearingsas the packers force the grain against the cord'untilthe bundle is completed, and when the needle moves to lay the other portion of the cord across the end it is gripped bythe holder where it will be engaged by the clamping ]5LWS and held during the operation of folding and squeezing the clip. The operation is substantially thejsame as shownand dej scribed in the Ware patent above-referredto and detailed description thereof is unneces sary.

When- ;the 'clip has been formed and' squeezed around the cordthe anti-friction roller 67 mounted on an arm'68 which is. secured to the shaft 6, will contact with'the' spring 65 and push the spindle 64. inwardly and release the end of the cord, and the cord holder being held in its open position, as

indicated in Fig. 7 the-needle on its return stroke will lay the cord therein and the sever ng knife will then perform'the severing operation. When the anti-friction roller 67 has passed outof contact withthe spring 65 the cord holder willclose, gripping the r cord again and the needlehavingreturned to its normal position the'parts will be in proper relation to described;
